# BearWave – Build, Deploy & Fehlerprotokoll
|
||||||
|
|
||||||
|
Stand: 2026-06-22 · Release-Version: **1.0.5** (AUR + Flatpak)
|
||||||
|
|
||||||
|
## Versionspolitik
|
||||||
|
|
||||||
|
| Was | Regel |
|
||||||
|
|-----|--------|
|
||||||
|
| **App-Version** (`CMakeLists.txt`, About, Flatpak-Manifest) | Nur bei echtem Release erhöhen (aktuell **1.0.5**, siehe `CHANGELOG.md`) |
|
||||||
|
| **AUR** (`PKGBUILD`) | `pkgver=1.0.5` beibehalten, bei Bugfixes nur **`pkgrel`** erhöhen (aktuell **8**) |
|
||||||
|
| **Flatpak** (`de.nerdbear.bearwave.json` → `version`) | Gleiche Versionsnummer wie Release (**1.0.5**), neuer Build = neuer OSTree-Commit |
|
||||||
|
| **Build identifizieren** | Git-Hash im About-Dialog (`BEARWAVE_GIT_HASH`), nicht die App-Version hochzählen |
|
||||||
|
|
||||||
|
**Fehler (2026-06-22):** Mehrfach fälschlich 1.0.6–1.0.8 eingeführt, obwohl GitHub/AUR bei 1.0.5 bleiben. Bugfixes brauchen **keine** neue Minor-Version.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## AUR bauen
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Im PKGBUILD-Verzeichnis (AUR) oder lokal:
|
||||||
|
cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr
|
||||||
|
cmake --build build
|
||||||
|
```
|
||||||
|
|
||||||
|
- Version kommt aus `project(bearwave VERSION 1.0.5)` in `CMakeLists.txt`
|
||||||
|
- Git-Hash: `src/CMakeLists.txt` → `git rev-parse --short HEAD` (lokal vorhanden)
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Flatpak bauen & deployen
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Vollständiger Build + Repo + optional Deploy
|
||||||
|
scripts/build-flatpak.sh --deploy
|
||||||
|
|
||||||
|
# Nur Re-Export (kein neuer Source-Build; finish-args ändern sich damit NICHT)
|
||||||
|
scripts/build-flatpak.sh --reexport-deploy
|
||||||
|
```
|
||||||
|
|
||||||
|
**Wichtig:** `--reexport` übernimmt **keine** Änderungen aus `de.nerdbear.bearwave.json` (z. B. `--device=dri`). Nach Manifest-Änderungen immer **vollen** Build ohne `--reexport`.
|
||||||
|
|
||||||
|
### Deploy-Ziel
|
||||||
|
|
||||||
|
- Server: `ragnar@hosting:/srv/www/flatpak.bearwave.app/index/public/`
|
||||||
|
- Es wird **`flatpak_repo/`** per rsync deployed, **nicht** `flatpak_build/`
|
||||||
|
- `bearwave.flatpakrepo` auf dem Server bleibt unverändert
|
||||||
|
- SSH-Host `hosting` hat `RemoteCommand` → rsync nutzt `-e 'ssh -o RemoteCommand=none -o RequestTTY=no'`
|
||||||
|
|
||||||
|
### GPG-Signierung
|
||||||
|
|
||||||
|
- Key: `AA1D2F0170800855` (über `BEARWAVE_FLATPAK_GPG_KEY` überschreibbar)
|
||||||
|
- `flatpak-builder --gpg-sign=…` und `flatpak build-update-repo --gpg-sign=…`
|
||||||
|
- Ohne `summary.sig` / `summary.idx.sig` schlagen Client-Updates fehl („BAD signature“)
|
||||||
|
|
||||||
|
### Git-Hash im Flatpak-Binary
|
||||||
|
|
||||||
|
`flatpak-builder` kopiert **kein** `.git` in die Sandbox → `git rev-parse` in CMake liefert sonst `unknown`.
|
||||||
|
|
||||||
|
Lösung: `scripts/build-flatpak.sh` schreibt `BEARWAVE_GIT_HASH` per generiertem Manifest (`.flatpak-builder-manifest.json`) in `build-options.env`. `src/CMakeLists.txt` liest `ENV{BEARWAVE_GIT_HASH}`.
|
||||||
|
|
||||||
|
### Runtime
|
||||||
|
|
||||||
|
- KDE **6.10** (`org.kde.Platform`), ersetzt EOL 6.6 / Freedesktop 23.08 (Issue #5)
|
||||||
|
- Branch im Repo: **`master`** (nicht `stable`)
|
||||||
|
|
||||||
|
### Finish-Args (aktuell)
|
||||||
|
|
||||||
|
- `--device=dri` – GPU/EGL-Zugriff (`/dev/dri`), ohne diesen: MESA/ZINK/EGL-Warnungen
|
||||||
|
- `--socket=wayland`, `--socket=fallback-x11`, `--share=ipc`, `--share=network`
|
||||||
|
- MPRIS: `--own-name=org.mpris.MediaPlayer2.bearwave`
|
||||||
|
|
||||||

|

|
||||||
|
## Installation (Endnutzer)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
flatpak remote-add --user bearwave-repo https://flatpak.bearwave.app/bearwave.flatpakrepo
|
||||||
|
flatpak install --user bearwave-repo de.nerdbear.bearwave
|
||||||
|
flatpak update de.nerdbear.bearwave
|
||||||
|
flatpak run de.nerdbear.bearwave
|
||||||
|
```
|
||||||
|
|
||||||
|
Nach Update bei seltsamen QML-Fehlern Cache leeren:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
rm -rf ~/.var/app/de.nerdbear.bearwave/cache/BearWave/BearWave/qmlcache
|
||||||
|
killall bearwave
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Bekannte Fehler & Fixes
|
||||||
|
|
||||||
|
### 1. AUR: `qrc:/qml/Main.qml not found`
|
||||||
|
|
||||||
|
**Ursache:** QRC-Prefix `/qml` + Pfad `qml/Main.qml` → Ressource unter `qrc:/qml/qml/Main.qml`.
|
||||||
|
|
||||||
|
**Fix:** Commit `a725430` – Prefix `/` in `src/qml.qrc`. Regressionstest: `tests/qrc_resources_test.cpp`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2. About zeigt 1.0.3, `flatpak info` zeigt 1.0.6+
|
||||||
|
|
||||||
|
**Ursache:** Zwei getrennte Quellen:
|
||||||
|
|
||||||
|
- `flatpak info` → AppStream-Metainfo
|
||||||
|
- About → laufendes Binary (`BEARWAVE_VERSION` / `Qt.application.version`)
|
||||||
|
|
||||||
|
Typische Fälle:
|
||||||
|
|
||||||
|
1. **Alte Instanz läuft noch** (Single-Instance über MPRIS/DBus) – Update ersetzt Dateien, Prozess bleibt alt
|
||||||
|
2. **AUR-Binary** (`/usr/bin/bearwave`) statt Flatpak gestartet
|
||||||
|
3. Früher: Metainfo aktualisiert, Binary auf Server noch alt (Commit-Mismatch)
|
||||||
|
|
||||||
|
**Prüfen:**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
flatpak info de.nerdbear.bearwave | grep -E 'Version|Commit'
|
||||||
|
which bearwave
|
||||||
|
killall bearwave && flatpak run de.nerdbear.bearwave
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 3. About / Manual+ / Edit öffnen nicht
|
||||||
|
|
||||||
|
**Symptom:**
|
||||||
|
|
||||||
|
```
|
||||||
|
HeaderNavigation.qml:112: TypeError: Cannot call method 'open' of undefined
|
||||||
|
```
|
||||||
|
|
||||||
|
**Ursache:** Seit QML-Refactor (2026-06-20) fehlten `property alias` in `Main.qml`. `HeaderNavigation` nutzt `app.aboutDialog`, `app.addDialog` – IDs allein exportieren keine Properties.
|
||||||
|
|
||||||
|
**Fix:** Commit `2de7706` (pkgrel 4):
|
||||||
|
|
||||||
|
```qml
|
||||||
|
property alias addDialog: addDialogPane
|
||||||
|
property alias editDialog: editDialogPane
|
||||||
|
property alias aboutDialog: aboutDialogPane
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 4. About: `String.arg(): Invalid arguments`
|
||||||
|
|
||||||
|
**Symptom:** Zeile in `AboutDialog.qml`, App startet teilweise (`Loaded 100 stations`).
|
||||||
|
|
||||||
|
**Ursachen (mehrere übereinander):**
|
||||||
|
|
||||||
|
1. **QML:** `qsTr("…%1…%2").arg(a, b)` – in QML nur **ein** Argument pro `.arg()`; korrekt: `.arg(a).arg(b)`
|
||||||
|
2. **Stale QML-Disk-Cache:** Altes kompiliertes QML in
|
||||||
|
`~/.var/app/de.nerdbear.bearwave/cache/BearWave/BearWave/qmlcache`
|
||||||
|
→ Fehler bleibt trotz neuem Binary
|
||||||
|
3. **Fix im Code:** String-Verkettung statt `.arg()`; `QML_DISABLE_DISK_CACHE=1` in `main.cpp`
|
||||||
|
|
||||||
|
**Cache leeren** (siehe oben) oder App neu installieren.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
### 5. Flatpak: EGL / MESA / ZINK-Warnungen
|
||||||
|
|
||||||
|
```
|
||||||
|
libEGL warning: failed to get driver name for fd -1
|
||||||
|
MESA: error: ZINK: failed to choose pdev
|
||||||
|
```
|
||||||
|
|
||||||
|
**Ursache:** Kein `--device=dri` im Manifest → kein `/dev/dri` in der Sandbox.
|
||||||
|
|
||||||
|
**Fix:** `--device=dri` in `de.nerdbear.bearwave.json` (voller Rebuild, nicht `--reexport`).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 6. `flatpak run` – „es passiert nichts“
|
||||||
|
|
||||||
|
**Ursachen:**
|
||||||
|
|
||||||
|
1. **Single-Instance:** Zweiter Start ruft nur `Raise` auf und beendet sich (`main.cpp`). Wenn `raiseRequested` nicht verbunden war (nur über Tray), passiert nichts Sichtbares.
|
||||||
|
2. **Fix:** `raiseRequested` immer an Hauptfenster binden; `show()` / `requestActivate()` nach QML-Load; MPRIS-Registrierung **nach** erfolgreichem QML-Load (Commit `872670b`).
|
||||||
|
|
||||||
|
```bash
|
||||||
|
killall bearwave
|
||||||
|
busctl --user list | grep bearwave
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 7. About: `build unknown`
|
||||||
|
|
||||||
|
**Ursache:** Flatpak-Build ohne `.git` → `BEARWAVE_GIT_HASH=unknown`.
|
||||||
|
|
||||||
|
**Fix:** `BEARWAVE_GIT_HASH` via `build-flatpak.sh` → Manifest-`env` (siehe oben).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 8. About-Dialog: Crash beim Öffnen
|
||||||
|
|
||||||
|
**Symptom:** About zeigt kurz „Version 1.0.5 · build unknown“, dann Absturz.
|
||||||
|
|
||||||
|
**Vermutliche Ursache:** `ScrollView` + `licenseScroll.availableWidth` unter KDE-Dialog/Flatpak (ungültige Breite beim ersten Layout).
|
||||||
|
|
||||||
|
**Fix (minimal, Layout unverändert):** Commit `315b5b6`
|
||||||
|
|
||||||
|
- `width: licenseScroll.availableWidth` → `width: Math.max(licenseScroll.width, 1)`
|
||||||
|
- `ScrollBar.AlwaysOn` → `ScrollBar.AsNeeded`
|
||||||
|
|
||||||
|
**Nicht tun:** Komplettes About-UI durch vereinfachtes Layout ersetzen (fehlerhafter Versuch in `a9f286b`, zurückgenommen in `315b5b6`).
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
### 9. PipeWire-Warnung
|
||||||
|
|
||||||
|
```
|
||||||
|
Failed to connect to pipewire instance "Der Rechner ist nicht aktiv"
|
||||||
|
```
|
||||||
|
|
||||||
|
Harmlos, wenn PulseAudio verfügbar ist. Kein BearWave-Bug.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 10. Flatpak-Deploy: rsync exit 23
|
||||||
|
|
||||||
|
```
|
||||||
|
rsync: failed to set times on "...": Operation not permitted
|
||||||
|
```
|
||||||
|
|
||||||
|
Meist nur Timestamp/Owner auf dem Webserver – **Deploy-Inhalt ist trotzdem angekommen**. `--no-group --no-owner` ist gesetzt.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 11. GPG Pinentry-Timeout beim Build
|
||||||
|
|
||||||
|
```
|
||||||
|
Failure signing commit file: Pinentry: Timeout
|
||||||
|
```
|
||||||
|
|
||||||
|
Build-Umgebung braucht funktionierendes GPG-Agent/Pinentry (interaktiv oder `loopback`).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## QML / Architektur-Hinweise
|
||||||
|
|
||||||
|
- Version im About: `Main.qml` → `appVersion` / `appBuildId` als Properties an `AboutDialog` (nicht auf globale Context-Properties im Modul verlassen)
|
||||||
|
- `setApplicationVersion()` **nach** `QApplication app(argc, argv)` in `main.cpp`
|
||||||
|
- Dialoge: immer `property alias` in `Main.qml`, wenn Kind-Komponenten sie über `app.*` ansprechen
|
||||||

## Checkliste vor Release/Deploy
|
||||||
|
|
||||||
|
- [ ] `CMakeLists.txt` Version = Release-Nummer (1.0.5)
|
||||||
|
- [ ] `PKGBUILD` nur `pkgrel` erhöhen, wenn kein neues Release
|
||||||
|
- [ ] `de.nerdbear.bearwave.json` `version` = gleiche Nummer
|
||||||
|
- [ ] Voller Flatpak-Build (`scripts/build-flatpak.sh --deploy`), kein `--reexport` nach Manifest-Änderungen
|
||||||
|
- [ ] GPG-Signatur auf Repo prüfen
|
||||||
|
- [ ] Lokal: `flatpak update`, Cache ggf. leeren, About + Manual+ testen
|
||||||
|
- [ ] `killall bearwave` vor Test, nicht AUR- und Flatpak-Binary gleichzeitig laufen lassen
